Description

Technical Field

[0001] This utility model belongs to the field of precision quantitative feeding technology, and specifically relates to a stable and continuous constant pressure and constant temperature feeding device. Background Technology

[0002] Some fluid media in existing feeding equipment are quite sensitive, such as curing agents, catalysts, and highly sensitive two-component adhesives, which require a constant temperature environment to achieve better chemical properties. Furthermore, the quantitative delivery of these media before they participate in the chemical reaction requires extreme precision. If the quantitative error is too large, it will result in excessive or insufficient quantities, leading to impure chemical products and affecting quality. Therefore, how to set up a precise feeding device is a technical problem that we urgently need to solve. Utility Model Content

[0009] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0010] 1. This utility model product is equipped with a heat-insulating and pressure-maintaining feeding tank, which keeps the feeding end at a constant temperature and pressure, thereby keeping the medium entering the metering pump stable and enabling stable metered discharge;

[0011] 2. The product of this utility model has an automatic switch valve at the bottom of the heat-insulating and pressure-maintaining feeding hopper. When the feeding hopper is short of material, the system can automatically switch to the feeding hopper that has been settled. This can effectively avoid the adverse effects of pulse, impact bubbles, temperature difference, pressure difference and other factors caused by replenishing material during use, and make the feeding process smoother.

[0012] 3. This utility model product adopts a double heat-insulating and pressure-maintaining feeding tank. Only one tank is used at a time, while the other tank has a static waiting function. The liquid material can be allowed to stand, maintain constant temperature and pressure, and defoam in the waiting tank beforehand. After a period of time, it can be automatically switched and activated as needed.

[0013] 4. The metering pump of this utility model adopts a servo motor, which further makes the metering more accurate. With multiple optimization measures such as pulse-free, bubble-free, constant temperature, constant pressure, and servo precision control, the accuracy of metering is guaranteed, and the purity and quality of the final chemical product are improved.
